The importance of copper as a supplement to iron for hemoglobin regeneration in anemic rats was first demonstrated 4 years ago by Hart, Steenbock, Waddell, and Elvehjem (1). This work showed definitely that in the presence of copper, soluble inorganic iron salts can be used directly for hemoglobin formation. Since that time a number of workers have studied factors affecting hemoglobin productio...

An increased mortality from lung cancer, cardiovascular disease, haematolymphatic malignancy and cirrhosis of the liver has been reported among smelter workers and others exposed to arsenic. This study uses the case-referent (case-control) technique and is concerned with workers in a copper smelter in a complex work environment, characterised by the presence of trivalent arsenic in combination ...

Objectives—To investigate the eVects of ethylene glycol monomethyl ether (EGME) on haematology and reproduction in exposed workers. Methods—53 Impregnation workers from two factories that make copper clad laminate with EGME as a solvent were recruited as the exposed group. Another group of 121 lamination workers with indirect exposure to EGME was recruited as the control group. Environmental mo...

Mining has been characterized by most researchers as one of the most hazardous occupations amongst major industrial activities. Despite regulations, automation and increased attention towards reducing risks through safety campaigns, the mining industry is still associated with higher rates of injuries compared with other industries. Mine workers must deal with a number of subtly harmful risks t...

there have been much speculation and debate concerning the effect of electromagnetic fields (emf) on body systems. various reports have implicated excessive exposure to emf to certain forms of leukemia. it has also been reported that emf may cause alteration in the levels of certain macro- and micro-nutrients such as copper, zinc, selenium, calcium and iron. we have undertaken this study to det...

In 1924, Hart, Elvehjem and coworkers demonstrated that copper is essential for erythropoiesis in most, if not all, mammalian species (1). Since that time many studies have been performed in attempts to elucidate the manner in which copper functions in erythropoiesis, but as yet this mechanism is not understood. Recent studies in this laboratory (2) have indicated that the amount of copper in t...
